Unfortunately, the kernel needs to know how much RAM you really have so
it can properly allocate memory resources.  Lying to it (by passing mem=)
is generally a recipe for disaster.

However, if slram is making use of some area of memory, it really should
reserve it.  That's a slram bug - please report it to the mtd mailing
list.

Even with slram fixed, there remains the danger of something trying to
allocate a resource _before_ slram claims its resource...  I just hate
the entire mem= mess entirely for this very reason.  It's completely
unsafe.
